Definitions
- the invention concerns imino-isoindolinone compounds having low solubility in water.
- the condensation is advantageously carried out in a polar organic solvent, for example in an alcohol, alcohol ether, N-dialkylacylamide or dimethyl sulphoxide.
- the reaction may conveniently be carried out at a temperature of upto 200C, preferably from to C.
- a neutral salt for example formed from a strong acid, such as the hydrochloride or sulphate salt of the compound of formula III, is employed.
- the free diamine'of formula III it is advisable to carry out the condensation in the presence of an acid, such as glacial acetic acid, which binds the ammonia liberated in the reaction. Since the condensation involves two mols of the compound of formula II to one mol of the.
- a signifies structure (b) and X signifies R preferably signifies an alkyl radical of l to 6, more preferably 1 to 4, carbon atoms.
- the compound of formula II, in which A signifies structure (a) is conveniently obtained by cleavage of hydrogen chloride, in conventional manner, from the compound of formula II in which A signifies structure (b) and X signifies
- the preferred compounds of formula I are those in which R and R independently, each signify a chlorine or bromine atom.
- the compounds of formula I are pigments. They are particularly suitable for pigmentation of synthetic polymeric materials in the mass, in the presence or absence of solvents, particularly after having been conditioned in the normal methods for pigments.
- synthetic polymeric material is to be understood synthetic polymers and resins such as polyethylene, polystyrene, polyvinyl chloride, synthetic rubber latices and peromerics (synthetic leathers).
- the compounds are also suitable for use in emulsion paints and other surface coatings in an oil, water or solvent base, in printing inks and in viscose and cellulose acetate spinning solutions for the production of spundyed filaments.
- the compounds can also be used for dyeing paper in the stock prior to sheet formation and for painting and coating textiles. In the above uses, the compounds of formula I are used in conventional manner.
- the compounds of formula I are notable for good transparency and heat stability characteristics, together with notable migration and light fastness properties and notable fastness to overspraying.
- EXAMPLE 1 32 Parts of 3-imino-iso-indolinone and parts of 2,5-dichloro-l,4-diaminobenzene hydrochloride are dissolved in 500 parts of ortho-dichlorobenzene and reacted for 16 hours at l-140 with thorough stirring. A yellow precipitate forms which is filtered off at 100 with suction, washed consecutively with hot orthodichlorobenzene, methanol and water, and dried at 100. The crude product is dissolved in a mixture of 500 parts of ethyl alcohol and 25 parts of 33 7c sodium hydroxide solution at 60. After the addition of activated carbon the solution is stirred for a short time and then filtered. The filtrate is acidified with 15 parts of acetic acid to precipitate the pigment, which is filtered off while still warm, washed with ethyl alcohol and water, and dried at 100.
- a pigment of high tinctorial strength with the formula is obtained. It is eminently suitable for the pigmentation of synthetic polymers and surface coatings and is notable for very good light and migration fastness, heat stability and fastness to overspraying.
- EXAMPLE 2 are listed which are produced in accordance with the procedure of Example 1 or 2.
- a polyvinyl chloride emulsion 32 parts of a dioctyl phthalate plasticizer 3 parts of a commercial epoxide plasticizer 1.5 parts of a commercial stabilizer (barium-cadmium complex) 0.5 parts of a commercial chelator.
- the mixture is worked for 8 minutes on a roller mill set at 160, with one roller rotating at 20 r.p.m. and the other at 25 r.p.m. to exert friction. Subsequently it is extruded as film of 0.3 mm thickness.
- the film is pigmented in a greenish yellow shade which has very good light and migration fastness and is heat stable.
- R and R which may be the same or different, each signifies a chlorine or bromine atom.
